Abstract

Upper bounds at the weak scale are put on all ${\ensuremath{\lambda}}_{ijk}^{\ensuremath{'}}{\ensuremath{\lambda}}_{imn}^{\ensuremath{'}}$-type products of $R$-parity violating supersymmetry that may affect ${K}^{0}\ensuremath{-}{\overline{K}}^{0}$ and ${B}^{0}\ensuremath{-}{\overline{B}}^{0}$ mixing. We constrain all possible products, including some not considered before, using next-to-leading order QCD corrections to the mixing amplitudes. Constraints are obtained for both real and imaginary parts of the couplings. We also discuss briefly some correlated decay channels which should be investigated in future experiments.
